Use of Sm(III)-{1,2-propanediamine-N,N,N',N'-tetra(alpha,alpha-dideuterioacetate)} complex for NMR determination of absolute configuration of each alpha-amino acid in peptide hydrolysate mixtures.
(1)H NMR analyses of individual alpha-amino acids in their mixture were simultaneously conducted in the presence of Sm-(pdta-d(8)) in water: high regularity, promising for direct simultaneous determination of absolute configurations of each alpha-amino acids in peptide hydrolysate mixtures, was observed between absolute configuration and the induced shifts.
